Ok Steve, I was satisfied with you answers even though I disagreed. Now your doing nothing more than pushing your Items on this board without any facts or stats. (This alone is against Forum policies) You are comparing a Turbo or Centifical supercharge to a rootsblower. Your also comparing a air to air cooler to a air to water. The reason it works so good is because you are spraying the alki in after the superheated air. When you spray the alki into ambient air, the same thing is going to happen when you spray alki into the air out of a squirt bottle. The alki doesnt evaporate, its just droplets falling in the air. Push these droplets thru a compressor and they form bigger droplets. These bigger droplets are now going to go into cylinder causing either a lean mixture or worse but possible, hydolock. In you 1st post you say:

Anyway....someone on the forum with access to a dyno needs to be the gunea pig. I'll send a $50 check for a dyno printout. Then you can quit guessing and know for sure if it works.

Well we are no longer guessing here, a member has stated he used it and got no results. You have to many variables to compare a Turbo/Air to Air Cooler with a roots/water to air.

 

Sounds like a very interesting thing to try.

Buzlightyear,
I don't think that hydrolock is possible unless you use a firehose. I've personally seen a 400 CI engine drink from a water house when the hose was on full.

I also can't see droplets recombining, especially at temps above 200 degrees.

Another benefit is that it would clean the intercooler, pistons, and valves.

 

Buzz:
Excuse me for throwing out the facts as they apply to turbo Buicks.....Trust me, I'm so busy I don't need extra business, I'm just trying to clear up misconceptions regarding OUR system. Just because someone used another brand of system that did or didn't work on his vehicle (need details please) doesn't mean that a proffesional system properly tuned (with added boost & timing) wont work on another truck.
As for alcohol evaporating......have you ever washed your hands with even rubbing alcohol?????? Gee, I wonder why it's so damn COLD even in ambient air temps????? Maybe cause it's EVAPORATING quickly???? About the only thing droplets of liquid alcohol will do inside the combustion chamber is greatly increase octane and clean your valves & pistons!
Jump in when you have some FACTS and not armchair physics that mean nothing in the REAL World.

 

As I had said before, this techonology as been around basically since they injected water into the engines of fighter planes in WWII. The technology is proven to work, we just don't know how well it will work in the Lightnings. Some tweaking may be required.

Also, it is not like using Nitrous where there is an instant gain of XX horsepower based on what nitrous jets are being used. The majority of the gains come out of being able to run added boost and timing.

****: Did you get that system installed yet??

 

I've run water injection in the past, including my last ProCharged engine. I've used it on centrifugal and roots-type blowers and it will be on my new twin turbo car.

I've always used plain distilled water although alcohol would have the benefit of a little additional octane plus since it burns could help out in a situation where you're at or beyond the limit of your injector size to get extra fuel into the motor. I had plenty of injector on my last projects so I used straight water as it is better at pulling heat out.

If you install water or water/alcohol injection on your truck but don't increase the boost or timing you will realize little benefit. There should be some air temp reduction, but the benefit of this injection is seen in the combustion chamber. Because it pulls out heat it allows you to run more boost and timing without detonation. That's where the power increase comes from, not from the water/alcohol itself.

I was running 16 psi of boost on a 540 with 28 degrees of timing on 91 octane California gas. This was with 9.44:1 compression. Yes, it was an all-aluminum engine, had coated pistons, and was a centrifugal blower instead of a Roots, but still...................
